Eaton Corp. has confirmed a 7 to 19% fuel economy advantage for its Fuller UltraShift HV (Highway Value) medium-duty transmission over conventional automatics based on recent independent tests done under SAE standards.

The tests, conducted by an independent firm, showed that in an urban setting requiring numerous stops and starts, the UltraShift HV transmission delivered fuel economy savings of up to 19%. The UltraShift HV transmission delivered 7.5% improved fuel economy in the SAE test protocol for on-highway operation.

“With the ever increasing cost of fuel and raw materials, companies throughout the trucking industry are looking for ways to reduce costs,” said Bill Gross, product manager for Eaton’s medium-duty transmissions. “The UltraShift transmission’s design provides a significant improvement in fuel economy, particularly in stop-and-go operations.”

The UltraShift HV is a fully automated transmission system that shares technologies and electronic components from the Fuller UltraShift heavy-duty transmissions. The HV is designed for Class 6 and 7 vehicles with diesel engines in the 195 to 260 hp. Range, and is capable of handling torque capacities up to 660 lbs./ft. and loads up to 33,000 lbs. GVW. Pickup & delivery, service/utility and recovery applications are ideally suited for the operational characteristics of the UltraShift HV transmission, Eaton said.

The UltraShift HV transmission will be available in January 2006 as a databook option on International Truck and Engine’s 4300 and 4400 model chassis with a DT 466, 225-hp engine. Orders for models equipped with the HV could be made today at International dealers for delivery in 2006, by asking for it as an “SQ” option, Eaton said.

Key features and benefits of the UltraShift HV transmission include:

  • No Scheduled Maintenance: No filters to change and “Lubed for Life” provides lower maintenance and downtime costs up to 500,000 miles.
  • Hill Assist: Automatically minimizes rollback on up to 10% grades while the operator makes the transition from the brake pedal to the accelerator.
  • Warranty: Warranty coverage, which varies by vocation, for up to three years, unlimited mileage, parts and labor.
